标题: 这语法哪里错了？
自己写的简单的小程序试着在51hei开发板上跑 结果提示语法错误

#include<reg52.h>
#define uint unsigned int 
#define uchar unsigned char
sbit dula=P2^6;
sbit wela=P2^7;
uchar num;
uchar code table[]=
{0x3f,0x06, 0x5b,0x4f,0x66,0x6d,0x7d,
 0x07,0x7f,0x6f,0x77,0x7c,0x39,0x5e,
 0x79,0x71};
void delay(uint z);

void main()
{
 wela=1;
 P0=0xc0;
 wela=0;
 while(1)
 
 {
 for(num=0;num<16;num++)
 { 
 dula=1;
 P0=table[num];
 dula=0;
 delay(1000);
 }

 }

 void delay(uint z)
 {
 uint x,y;
 for(x=z;x>;x--)
 for(y=110;y>0;y--);
 }

 for(x=z;x>？？？？ ;x--)

 }
 } //这里掉了一个括号

void delay(uint z)

 for(x=z;x>0;x--)  //这句掉了一个0
 for(y=110;y>0;y--);
 }
